Abstract
A lenticular lens sheet,A comprises, on the light-entering surface thereof, a light-entering lens part in which a plurality of light-entering lenses,are formed, and, on the light-emerging surface, a light-emerging lens part in which a plurality of light-emerging lenses,are formed. The light-emerging lenses,are so arranged that they respectively correspond to the condensing positions of the light-entering lenses,. Further, a protruded portion,A having a substantially rectangular cross section is formed on the light-emerging surface, at a position corresponding to the non-condensing position of each one of the light-entering lenses,, and a black stripe,is formed on the top face,of this protruded portion,A by the application of a light-absorbing agent. The light-entering lens,is in the shape of a convex lens projecting toward the light-entering side, and so designed that its condensing point will be inside the lenticular lens sheet,A. Further, the light-emerging lens,is in the shape of a concave lens projecting toward the inside of the lenticular lens sheet,A. By this, it is possible to make the lenticular lens thick while keeping the pitch thereof fine, and, moreover, to increase the black stripe rate.
